PCSX-R in Ubuntu 18.04 cannot configure controllers when more then 1 gamepad is connected

[Josefien]

On Ubuntu MATE 18.04 you can't configure controllers in PCSX-R (package pcsxr from the official repositories) when more then 1 USB game controller (standard USB HID device) is connected to the PC.

There's just nothing happen when "Configuration" => "Controllers" is clicked in PCSX-R if there is more then 1 game controller connected to the PC.

When only 1 game controller is connected then it's fine.

Older Ubuntu MATE 16.04 don't have this problem.

Also: on 16.04 the configure-screen shows the controller manufacture/model in the list, in 18.04 it only shows "1: null" when one controller is connected. More controllers connected = the configure-screen can't even get opened.

It looks like the problem lies in the newer input-plugin (1.2.0) which is delivered with the pcsxr package in 18.04. In older 16.04 pcsxr package the plugin is version 1.1.0.

A dirty solution is to copy the old plugin files from Ubuntu 16.04 to 18.04:

Overwrite "cfgDFInput" and "libDFInput.so" in "/usr/lib/i386-linux-gnu/psemu" on 18.04 with the older files from 16.04.

Take /usr/share/psemu/dfinput.glade2 from 16.04 and put it in the same location on 18.04. Then install libglade2-0 package and the pcsxr in 18.04 will work with 2 or more USB gamepads connected using the older 1.1.0 input plugin.

How is this "invalid"? I've tested this on three different PC's with Ubuntu MATE 18.04 (both 32 and 64 bit) and all three are showing this problem.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug still exist in PCSX-R included in Ubuntu 20.04 LTS 64-bit. And still can work around using the files from Ubuntu 16.04 64-bit.

Why it this bug still not fixed?

Thanks to @josefien1989's detailed description of the workaround, I tracked this bug down to misuse of the SDL API.

Patch tested on Ubuntu Focal.
